MP6KE30CAE3 Equivalent & Substitute Parts

Part Overview

The MP6KE30CAE3 is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component operates with a reverse standoff voltage of 25.6V and provides clamping at 41.4V with peak pulse current handling of 14.4A. The device is qualified to MIL-PRF-19500 military standards and maintains active product status. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific packaging or thermal requirements necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6KE30CAE3 are identified based on electrical parameter equivalence within the transient voltage suppressor category. The critical parameters determining substitution compatibility are:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 25.6V
• Voltage - Clamping (Max) @ Ipp: 41.4V
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1

Mechanical Parameters:

• Mounting Type: Through Hole
• Package Type: Axial configuration

The P6KE30CA from Diotec Semiconductor meets these electrical specifications with identical standoff voltage, clamping voltage, and power rating. Both devices function as bidirectional Zener TVS diodes in through-hole axial packages. The substitute part accommodates peak pulse currents of 15A, which exceeds the 14.4A specification of the primary part, providing equivalent or superior performance within the same voltage protection envelope.

Parameter Comparison

Engineering Selection Recommendations

MP6KE30CAE3 (Primary Part): The MP6KE30CAE3 maintains active product status with military-grade qualification per MIL-PRF-19500. This part is suitable for applications requiring military-specification compliance and operates across an extended temperature range of -65°C to 150°C. The T-18 axial package provides standard through-hole mounting compatibility. RoHS non-compliance status should be evaluated against application requirements.

P6KE30CA (Substitute Part): The P6KE30CA from Diotec Semiconductor provides electrical equivalence with identical voltage protection parameters and superior peak pulse current capability (15A versus 14.4A). This part operates across a temperature range of -50°C to 175°C, extending the upper thermal limit by 25°C. The DO-15 (DO-204AC) axial package maintains through-hole mounting compatibility with standard PCB layouts. Selection of this substitute is appropriate when military qualification is not required and extended upper temperature operation is beneficial.

Both parts share identical critical protection parameters and axial through-hole mounting configurations, enabling direct functional substitution within the specified electrical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the P6KE30CA directly replace the MP6KE30CAE3 in existing designs?

A: Yes, the P6KE30CA provides electrical equivalence across all critical transient voltage suppression parameters: 25.6V reverse standoff voltage, 41.4V clamping voltage, and 600W peak pulse power. Both devices are bidirectional Zener TVS diodes in through-hole axial packages. The primary design consideration is package footprint compatibility between T-18 and DO-15 packages, which are both standard axial configurations suitable for through-hole PCB mounting.

Q: What is the difference in peak pulse current handling between these parts?

A: The MP6KE30CAE3 handles 14.4A peak pulse current, while the P6KE30CA handles 15A peak pulse current. The substitute part provides 0.6A additional current capacity within the same 600W power dissipation envelope, representing equivalent or superior performance for transient suppression applications.

Q: Are there temperature range differences between these parts?

A: The MP6KE30CAE3 operates from -65°C to 150°C junction temperature, while the P6KE30CA operates from -50°C to 175°C. The substitute part provides a 25°C higher upper temperature limit, which may be advantageous in high-temperature environments. The lower temperature limit of the substitute part (-50°C versus -65°C) should be evaluated for applications requiring extended cold-temperature operation.

Q: Does the P6KE30CA meet military qualification requirements?

A: The P6KE30CA does not carry military qualification per MIL-PRF-19500. The MP6KE30CAE3 is qualified to this military standard. Applications requiring military-specification compliance must use the primary part number or identify alternative military-qualified sources.

Q: What are the package differences between T-18 and DO-15?

A: Both T-18 and DO-15 are through-hole axial package configurations suitable for standard PCB mounting. The DO-15 (DO-204AC) is a widely standardized package format. Physical dimensions and lead spacing should be verified against specific PCB layout requirements, though both packages accommodate conventional through-hole assembly processes.

Q: Are there RoHS compliance differences?

A: The MP6KE30CAE3 is RoHS non-compliant. The P6KE30CA RoHS status is listed as not applicable. Applications subject to RoHS compliance requirements should evaluate the P6KE30CA or identify RoHS-compliant alternatives from the manufacturer.
